You are right about removing the motor mount. You have to support the engine with a jack. Use a piece of plywood between the jack and the oil pan. Remove the motor mount and you should be able to lift the engine up about 2-3 inches with the jack. Remove the serpentine belt and then you should have enough room to remove the alternator.

SOURCE: Will not charge

you will get some funny answers from some of these "experts " The symptoms suggest to me with out much doubt that the regulator is not doing its job correctly ,consistently.Iwould take it to an AUTO ELECTRICIAN and get it tested in situ.... there is only 4 things it can be , wireing ---battery---alternator-----regulator and of those the reg. is the only one that chops and changes. it will cost little for a sparky to check the reg ,. AND I WOULD LIKE TO KNOW THE OUTCOME

Replace the Alternator. Sounds like the internal brushes have worn out as you appear to have the correct feeds to it. If you are tempted to open the alt to have a look at the brushes, be careful as incorrect assembly can cause serious damage as can incorrect re-assembly. You can simply replace the brushes but I would advise against it as the copper rings the brushes rub on (the slip rings) will also be worn and require replacement, this is difficult if you do not have the experience. Also, the bearings should also be replaced as they will no doubt be worn too. Altogether a specialist job, so grab yourself an new or exchange alternator. if you have to get a second hand unit, have it tested BEFORE you fit it..

Why isnt my 1990 chrysler new yorker fifth avenue altenator not charging battery

Could be a bad battery or a bad alternator, or both.

A bad battery can hinder the performance of an alternator and a faulty alternator can slowly kill a battery.

Check your battery fluid levels and acidity concentration. Do not replenish fluid level with plain tap water as it will finally spell doom on the battery.

If you can still drive the car, take it to your nearest auto parts dealer. They usually have basic maintenance checkups for free. One of them is testing the charging system and they will tell you right up if the problem lies in the battery or the charging system.

A bad battery is a blind alley. If it's bad then replace it.

If you still want to hack at it at home, and all is OK with the battery, there is an old way of telling whether the alternator is working properly. But it's kind of dangerous if you do it wrong.

With the engine running, place the flat part of a flat head screwdriver on the side of the alternator, opposite to the v-belt or serpentine pulley. I'm talking about the center of the back cover of the alternator. Make sure you do not touch any electrical connections with the screwdriver as you may cause a short-circuit and experience fireworks. The tip of the screwdriver should be safely away from any spinning pulleys and belts.

If you feel a magnetic 'pull' on the screwdriver from the alternator body at the center of the back cover, it is a good sign that it is actually doing its job, charging that is. But only that.

An alternator "alternates" between powering all things electrical in your car and charging the battery. There is a small, replaceable thing called a "voltage regulator" that when it goes bad, it kinda gives you battery problems. You can buy one and replace it yourself or you can have someone do the dirty stuff.

In any case, a good, professional, clean, and thorough checkup is always the best option.

Hope it helps.

I am getting P0622 on my Chrysler Town and Country. I have a brand new battery and the alternator tested good at Auto Zone. I got 12.4 volts at the battery with the van off and between 7 and 8 volts...

if you getting 12.4 volts with no power load and engine goes down to 7-8 volt should be between 13-14 volts on idle would say the voltage regulator has gone.some are replaceable but most are not so you will need a new alternator or a secondhand one that is know to be working.
